3.5 - Air Conditioning ( )

The system under the bonnet is conventional and appears reliable. The compressor is located on the lower front left side of the engine, viewed from the front, and is driven from the engine auxiliary belt via an electrically controlled magnetic clutch.

There is an inline fuse visible on the wiring to the compressor clutch, which is fed from a relay located behind the headlights.

The pressure switched for the system can be found on the pipes towards the rear of the engine bay on the left side. These control the operation of the electric cooling fans, as described under ‘Cooling System’, and also protect the compressor by preventing it’s operation if refrigerant pressure is too low, typically following a leak.

Diagnosis of this can be done from the climate control panel, as detailed in 11.3 below.

To keep the seals in good condition, and therefore keep the refrigerant inside the system, it is important to run the a/c frequently even though it may not be needed for cooling purposes. Five minutes use every couple of weeks is all it takes to keep them lubricated and healthy.
